4 Claims (01. 4-217) vices have not succeeded in fulfilling the Pu p sel desired and it is understood that the main reason contributing to thisfailure is the fact that there no effective means within the bowl itselffor Accord- Y ingly, it is the purpose of the present invention toprventing the escape of such gases.

provide a toilet bowl which will avoid this difficulty and at the sametime not appreciably increase the initial cost of the equip t, and

' which will not in any wis'e add to the stallation thereof.

In addition to the foregoing objectives it is the further purpose of theinvention to provide this desired and needed element to bathroomequipment by a novel arrangement wherein the following advantages arealso added, to wit:

A. To provide a toilet bowl having means incorporated within theinternal structure thereof for carrying oil noxious gases.

B. To provide a device which may be interposed between the bowl and seatof an installed 0 fixture without appreciable expense which willaccomplish the purpose intended, and:

C. To further construct the apparatus within the seat proper of thetoilet fixture and which may be readily applied to toilet equipment nowitself as desirable for adoption by the public in general.

The invention is shown by way of illustration in the accompanyingdrawings wherein: Figure 1 is a side elevational view thereof.

Figure 2 a horizontal sectional view on a plane through the top of thebowl.

Figure 3 a transverse sectional view on the line 3-3 of Figure 2.

Figure 4 a side elevational view of a modifiedv construction. I

Figure 5 a transverse sectional view of the construction shown in Figure4.

Figure 6 a horizontal sectional view of a further modified construction..3

Figure? a transverse sectional view of the construction shown in Figure6; and, v

Figure 8 is a diagrammatic illustration of the system as applied to abuilding. Referring to the construction in further detail and whereinlike reference characters designate corresponding parts in the differentfigures shown, 8 represents an ordinary bowl, the top portion III ofwhich has the usual water channelway H for the ordinary flushing systemand at its upper rim portion there are located two outer channels l2that terminate with enlarged or flaring openings l3 located adjacent thefront portion of the bowl, and at the rear there is a similar pair ofchannels ll having enlarged inlet openings I! as shown. Said inner and.outer channels are evenly located on opposite sides of the bowl andtheir obvious function is to conduct noxious gases therefrom into acommon discharge l6 whence they are conducted by pipe H to a blower l8having discharge flue l9 that communicates with a vent or outlet fiuc 20that extends through the building and discharges into the atmosphere.

The ordinary seat 2| and cover therefor 22 is provided and to obtain thedesired hermetic sealor air-tight closure between the seat proper andthe bowl there is a strip of rubber 23, or other suitable material solocated that'the desired airtight condition is obtained.

In the construction shown in 4 and 5 the invention is characterized inthat the bowl portion 9Ill is not appreciably enlarged beyond itspresent proportions, but the top or rim surface 24 is substantiallyhorizontal or flat to the end of having mounted thereon thecorrespondingly shaped part or section, 25 that is formed with pairs ofinner and outer channel-ways l2 and I5 substantially after the mannershown and described above with reference to Figures 1 and 2. Said partor portion 25 constitutes a unit in itself that may be fitted orinterposed between the bowl portion l0 and the seat 2| and thereby thefull advantages of the device may be obtained without the necessity ofconstructing or modelling the special type of bowl as indicated inFigure 1. In this instance the unit or portion 25 interposed between thebowl rim Ill and the seat 2| is fitted both above and below with pliablestrip members 26 and 21 and thereby the requisite seal between theseveral parts of the bowl construction as a unit are obtained.

Referring to the construction shown in I'igurea 6 and 7 the invention ischaracterised in that the exit fiues or channel-ways are provided withinthe seat structure 28 and in this instance said channel-ways 20-40 aredesigned after the manner shown in Figure 'l but are furthercharacterized in that their respective communications within the bowlproper are by means of a plurality of sma'll vents or ducts 8| which areguillcient in number and communicate within the bowl proper as shown.The seal between said seat proper It and the rim of the bowl top portionit is here also obtained by means of the pliable or strip of insulationI! that is interposed between said parts as indicated.

It will be understood the invention as herein disclosed is not limitedto the details of construction shown and described, since these may bevaried without departing from the principles of the invention as definedby the claims.

What is claimed as new is:

1. A ventilated toilet fixture comprising a bowl, and a membersuperimposed upon the bowl and conforming in contour to the rim part ofthe bowl, said member being constructed with outer and inner channels ateach side thereof having outlet ends opening through the rear portion ofsaid member and having inlet ends opening through the inner face of saidmember respectively at spaced points in front and rear of the transversecenter thereof, said member having 8.

4. A ventilated toilet fixture comprising a bowl having a level top rimportion, a seatmember having a base portion provided with a plurality ofchannelways to carry of! noxious gases, said channelways extendingvertically between the top and bottom of said basev portion and havingoutlet ends opening through' the rim of the base portion and inlet endsopening through the inner side of the base portion at the front and rearthereof, and hermetic seals interposed between said rim and the baseportion of the seat and between the seat and its base portion.
